Furthermore, Sichuana differs from Uvarovina Ramme, 1939, Ptosoproctus Shen, Yin & He, 2021, and Eulithoxenus Bey-Bienko, 1951 by its prosternum with a pair of spines (Figs 4, 8, 11, 14). Differs from Atlanticus Scudder, 1894, Eulithoxenus, Ptosoproctus, and Uvarovina by its ovipositor being decurved (Figs 2, 6, 9, 12). Differs from Atlanticus, Eulithoxenus, Mongolodectes Bey-Bienko, 1951, Paratlanticus Ramme, 1939, Ptosoproctus, and Uvarovina by its lateral carina being distinct in metazona and faintly indicated on prozona (Figs 2, 6, 9, 12). Differs from Kansua Uvarov, 1933, Paratlanticus, Ceraeocercus Uvarov, 1910 by dorsal side of protibia only with external spurs, and dorsal side of mesotibia with spurs on both sides.
